Harvey Gulf International Marine has selected ABS as the class society for its four new dual fueled LNG-powered offshore supply vessels (OSVs) being constructed at Trinity Offshore LLC. The vessels will be among the first to be classed under the ABS Guide for Propulsion and Auxiliary Systems for Gas Fueled Ships released in May of 2011.
Shane Guidry, Harvey Gulf International Marine Chairman and CEO comments on the strong relationship between Harvey Gulf and ABS, “We have been working with ABS for a long time; our people know their surveyors and engineers, and in turn ABS is familiar with us and our vessels. Since these will be the first dual fueled LNG-powered vessels under the US flag, the strong relationship ABS has with the US Coast Guard, as well as ABS’ experience with dual fuel propulsion are also of great value to us.”
The LNG-powered OSV will introduce an innovative environmental solution to the US Gulf of Mexico. “This is likely to be the beginning of a trend for OSVs in the region. The availability of LNG and the implementation of the US Emission Control Area (ECA) starting in August 2012 make it a natural choice for fuel both from the commercial and environmental point-of-view,” says Kirsi Tikka, ABS Chief Engineer and head of the society’s environmental business activities. “ABS has the technology and the experience needed for this project and we are pleased to assist Harvey Gulf in this effort. The application of the Guide for the project will be another example of ABS providing environmental solutions to the industry while maintaining its safety focus,” comments Tikka.
The project will benefit from ABS’ vast experience in the OSV market and its industry-leading knowledge of LNG propulsion. “ABS has experience with a number of existing LNG carriers with dual fuel propulsion. In addition, nearly three-quarters of LNG carriers on order today will be built with dual fuel capabilities and ABS will be classing almost half of them,” says Tikka. “The application of dual fueled LNG-powered propulsion to OSVs will be an extension of our 60-year experience in the safe and efficient use of LNG.”
The use of LNG as fuel requires new technical solutions associated with the fuel storage, engine and piping arrangements, as well as the bunkering systems. To manage the complexities of the project, ABS has assigned a dedicated project manager and technical team to oversee the vessels’ construction. “This team will work with Harvey Gulf, Trinity Offshore and the vendors to support the development of design in compliance with the ABS Rules and regulations,” explains Tikka.
The supply vessels are also to receive environmentally-friendly notations from ABS, including ENVIRO+ denoting that the vessels adhere to enhanced environmental standards, POT for the protection of fuel and lubricating oil tanks and the green passport notation, GP.
Founded in 1862, ABS is a leading international classification society devoted to promoting the security of life, property and the marine environment through the development and verification of standards for the design, construction and operational maintenance of marine-related facilities.
